SATA “Y” Bridge with RAID IP Core – IPP-SA111-BR

The IntelliProp IPP-SA112A-BR SATA “Y” Bridge with RAID design provides SATA compliant connections and a standard SATA interface that performs RAID0 to provide higher performance media access for high speed data paths. The SATA “Y” Bridge can improve performance and increase the amount of storage by aggregating several drives to one for a customer high speed data system. The SATA host port and the direct access port are selectable via a port select pin. The direct access port, host and device connections are speed independent allowing for speed bridging to the SATA connections.

Functional Description

The hierarchy of the SATA Y-Bridge with RAID design can be divided into 3 main blocks:

SATA Device Port (contains SATA Host Cores + RAID Engine)

SATA Host Port (contains a SATA Device Core)

AMI port and Port Selector

The SATA Host cores are used with the IntelliProp RAID engine to stripe data across multiple drives and to increase throughput. The transfer rate can be as high as the aggregate throughput of all the drives connected.

The Y Bridge has an Alternate Media Interface (“AMI”) port that customers use to access the drives in a RAID 0 configuration. These drives can be read or written. Once the switch is activated, all control transfers to the SATA Device core to allow drive access to the Host PC.

The SATA Device core is used to communicate to the Host PC. This access remains in reset until the customer activates the switch. While this port may become a bottle-neck, it may be used to access the drives in a secondary way.
